This document describes the TIMEKEEPER family of products from STMicroelectronics, which include non-volatile RAM (NVRAM) and a real-time clock (RTC), offering dedicated time-keeping and alarm functions. The document provides detailed information on the storage and access of time information, as well as the handling of century rollover.

This application note describes a more maintenance-free way to sustain the data and clock in systems that only experience short breaks in the power supply (on the order of days). A Super Cap can be used as a type of secondary cell (a rechargeable battery) and can therefore provide an alternative solution to using a primary cell

This is an application note about the SPC564Axx / SPC563Mxx series of products, mainly introducing the hardware design guidelines for this series of products, including power management controller, FMPLL and oscillator, configuration pins and unused IOs, ADC and reset.

AN4057 is ST's application note about SPC560Pxx/SPC56APxx microcontrollers power on HW guideline. The application note gives design references to ensure a reliable microcontroller power up sequence also in the condition of an offset voltage on the high voltage regulator supply pin VDD_HV_REG at power up.

This application note describes how to program the Flash of SPC56x devices through the Nexus/JTAG protocol.

This application note details the steps required to properly initialize the SPC564Bxx and SPC56ECxx from reset as well as how to control the second core.

This document describes the external voltage regulation circuit of L99PM62GXP and its characteristics, including two circuits with external PNP and external NPN without current limitation, and circuits with external PNP and NPN current limitation.

This document compares the hardware and software differences between two 32-bit automotive microcontrollers, SPC560P50 and SPC56AP60. It covers the differences in device pinout and pin multiplexing, clock distribution and management, Flash memory, etc.

The L9942 is an integrated bipolar stepper motor driver primarily used in automotive headlamp leveling. It can also be used for other stepper motor operations. This application note explains the advantages of using Back Electro-Motive Force (BEMF) as a method for determining rotor or armature stall conditions.

This application note describes how to implement the power-on self test features in locked step on SPC56EL60

AN3316 is an ST application note that introduces the power management of SPC560B series products. This note introduces the low-power modes of the SPC560B series products and provides example firmware for implementing and measuring the power consumption and wake-up time of the different SPC560B series working modes.

This application note describes how to reach the highest level LQFP144 pin compatibility when designing an application with SPC560Px and SPC56EL60 devices.

This application note provides hardware design guidelines for SPC560B4x/5x and SPC560C4x/5x, including requirements for power supply, reset control, clock management, boot mode setting, debug management, and I/O settings.

This application note explains how to use the analog-to-digital converter implemented in the STM8A microcontroller family. The document provides useful information on how to configure the ADC registers and microcontroller resources and use the analog-to-digital converter in different modes.

The PJ-B2980 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. Systems designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing requirements.
